Security forces in Afghanistan have killed 30 suspected insurgents in a series of clashes around the country.

The army, police and Nato troops have launched 11 operations in the past 24 hours across Afghanistan. Seven insurgents were arrested.

The insurgents who were killed were armed and weapons were recovered in the operations.

Nato said one of its helicopters crashlanded in Nahr-e-Saraj district of Helmand province in a separate incident today after taking small-arms fire from the ground. There were no injuries among the crew.

Nato relies on helicopters to avoid using roads that are frequently mined by the insurgents.
